A nurse is caring for a child who has had diarrhea for 3 days.Which of the following actions should the nurse take?

Choice A rationaleCollecting a stool culture is important for identifying the causative agent of diarrhea, such as bacteria, viruses, or parasites. This information is critical for determining the appropriate treatment and managing the child's symptoms effectively.Choice B rationaleOffering apple juice or other sugary drinks can exacerbate diarrhea by drawing more fluid into the intestines and increasing stool frequency. Oral rehydration solutions are preferred.Choice C rationaleKeeping the child NPO (nothing by mouth) for an extended period is not recommended, as it can lead to dehydration and does not address the underlying cause of diarrhea.Choice D rationaleWeighing the child weekly is not sufficient for monitoring the immediate effects of diarrhea, such as dehydration and weight loss. More frequent assessments are necessary during acute episodes.
